I was searching for knee reflex levels 😅i thought i wasn't attentive lol he missed it

Honestly didn't there were students forgot that this is for studies

I've watched a few of the Stanford videos and this doctor seems like he'd be such an amazing teacher. I'm not even interested in medicine and I'd want to take his class.

[@bethramsfranklin4452]

he is

[@DoctorsHub]

reido82: Of course, he is a wonderful teacher.

[@SuyashJ]

Doctors Hub he's a really famous writer too! What a fantastic teacher!

[@chrisryan5798]

Check out the vide he did with zdoggmd

[@EDarien]

I've learned more from him than my actual professors in PA school. Highly recommended and seeing the difference from a real ranked school vs 150th.

[@danielturski7620]

1.) The Doctor's name is Dr Abraham Verghese. He's a General Internist who works at Stanford. He also has a fabulous TED talk on the value of the physical exam. I highly recommend it. 2.) Re: the unprovoked reflex at 4:27 in this video, the gentleman being examined is still a "simulated patient", which means he's been hired to play the part. Consequently, there will be acting. But whether the hammer hit his patellar tendon or not, he's still performing the exam correctly - swinging the hammer correctly, and aiming it at the right spot.

[@dougspizman6751]

No need 2 watch. Doctors haven't done physical exams in 20 years. Its 3-5 min and your out of there. Its about patient volume now. If I watch his TED talk it will only exaggerate what is missing.

[@CrazyAsianDude]

@@dougspizman6751 It varies in your doctor's choice. And your doctor's specialty. And depends if you're in the clinic or hospital setting. Believe it or not there are still good doctors.

[@acx2009]

Hold on. 4:27 - he doesn't even seem to make contact? that's some reflex.

[@TeetoPlastic]

You're right. That's frustrating. I guess the person in the demo's just a real people-pleaser.

[@musicaltheatergeek79]

Barba Ro, how do you mean?

[@TeetoPlastic]

How do I mean, what? The "people-pleaser" bit? Because it looks like he made a reflex action without any contact. Doing it for appearances and so the doctor "doesn't get upset." People-pleaser.

[@channelwonnews4322]

I'm sure the physician isn't a chump... however it would have been nice if the guy on the table 0:40 wouldn't a been such a cheating faker face~! How many other reflexes did he accentuate? I knew there was something funny about that reflex, but I didn't pause the video to analyze it. Peace.

Note: Deep tendon reflexes are still present in zombies.

[@shredlockholmes4408]

Also present in garden gnomes

They should disable comments because of nonsense like this.

[@rotcod2886]

(singing) A little nonsense now and then, is relished by the wisest men.

[@TeetoPlastic]

Rotcod Nonsense, though relished it may be, has no place when with the MD. Also: I think Neil Degrasse Tyson dispelled with zombie nonsense once and for all on the Daily Show. I invite you to find it for yourself.

[@melcat713]

Barba Ro Wow. Are you already an MD? I wouldn't go to you. Ever. Docs that think like you suck.

[@andreasenderoff4417]

we think you're really skilled at this!

[@cecigalvis2108]

What is the difference between tapping directy on the tendon and tapping over the examiner's thumb?

[@jakeabc123]

Tapping over the thumb helps you feel for contraction in case the reflex is diminished or trace and you can’t visibly see it well.

[@maxjach6056]

They didn't do that right; neither the doctor nor the patient got red in the face.

[@c4sh3w]

Because this is only reflexes and not strengh.

[@timelocked1366]

[@sonsofbiscuits1]

I haven't seen one "Navy Suit for War". Disappointing...

[@rodrigoferreira1175]

4:27 Is it my impression or the patient delivered a contraction without actually being hit by the hammer?

[@MegaCaprice123]

Rodrigo Ferreira yes, I see that. The knee was not hit, yet there was a reflex.

[@MegaCaprice123]

Or the hit was really light,

[@Mareyes2525]

Yep, it looked awkward so I had to slow down the video to see. Seems like his patient was instructed to fake all the reflexes. Fail communication between the two.

[@rodrigoferreira1175]

Yes, I think that might have been the case. Even though these contractions are primarily involuntary, they provoke some inner instinct that makes us uncomfortable, and we don't want to feel that again. After all, our reflexes exist to protect us, and nobody gets protected if no harm is detected. So the reflexes might automate without physical, but emotional (fear) stimuli.

[@CemZoun]

Considering the frame rate is 30 fps it might just be an impression

[@williamwinder5011]

One thing of note. A doctor must be proficient in being able to elicit reflexes. It is never appropriate to say I'm no good at it, I just can't get them, and so forth. A doctor must be able to see the reflexes in all patients other than those who simply do not have those reflexes for one reason or another.

[@Kim-kd8or]

I agree. I had a Doctor do that with me on two different occations when i had a stroke this year at 32 saying oh i am not good at the reflexes or i do not have a hammer i am not good at them anyway i can just slap and see if we get anything!! With a stroke !! In neurology ! Can you imagine ! I am a senior nurse and perform them better ! I am still shocked about this.
